Gamma-aminobutyric acid (GABA) is a neurotransmitter that reduces neuronal excitability and controls the speed of information transmission in the nervous system. It's the primary inhibitory neurotransmitter in the central nervous system, and is known for its calming effect.

GABA

Function

Inhibits neuronal firing, maintains respiratory rate, and integrates excitatory proprioceptive signals

Effects

Produces a calming effect, and is thought to play a major role in controlling anxiety, stress, and fear

Associated conditions. Research has shown that decreased GABA levels are associated with neurological and mental health conditions, such as Alzheimer's, Parkinson's disease, anxiety, depression, and stress.

Potential uses

Increasing GABA levels may help treat high blood pressure, diabetes, insomnia, premenstrual syndrome (PMS), and attention deficit hyperactivity disorder (ADHD)
